Namibian Wildlife Surveys archive
This archive of reports of wildlife surveys in Namibia aims to:
- provide easy public access to published information and statistics
- enable easy stakeholder access to recent and historical data on wildlife populations
- provide a comprehensive archive of wildlife survey reports in Namibia
Public access to information is a vital component of ensuring community engagement in prevalent issues. Wildlife surveys are critical to determine the health of wildlife populations and determine trends over time to guide conservation and management actions.
Wildlife surveys are done for different species using methods that are suited to counting them (e.g. by air or road) in their natural habitats. Such surveys need to be repeated over time to detect long-term trends and inform conservation managers. The Namibian government, non-governmental organisations and private reserves all conduct regular surveys covering different parts of Namibia and targeting different species. This archive will thus serve as a repository of our collective knowledge of the trends and status of a variety of species occurring throughout Namibia.

Estimates were calculated using DISTANCE which takes account in drop-off in detectability of animals with distance from the transect line. Where there are no values too few observations were recorded to allow for meaningful estimates to be derived. Attempts should be made to fill these gaps. Kwandu conservancy differs from the other 3 more strictly protected areas in that it contains a significant human presence. It is not expected to have the same species densities, but it is an important wildlife corridor between the national parks.

Accurately estimating hippopotamus (Hippopotamus amphibius) numbers is difficult due to their aggressive nature, amphibious lifestyle, and habit of diving and surfacing. Traditionally, hippos are counted using aerial surveys and land/boat surveys. We compared estimates of numbers of hippos in a lagoon in the Okavango Delta, counted from land to counts from video taken from a DJI Phantom 4TM drone, testing for effectiveness at three heights (40 m, 80 m, and 120 m) and four times of day (early morning, late morning, early afternoon, and late afternoon).
